Need advice on 730 cutting out occassionally

Sounds like the fuel is sloshing in the bowls causing the cutting out. My 36's do it when I run up the big, whooped out hill in one of the trail systems we ride.

so how do you fix that?

Avoid steep, whooped out hills, lol.
There were a few members that installed some sort of shield on the main jets, and a few ran spacers between the bowl and carb body to drop the main jet further into the fuel. Don't know if any of these mods cured the issue though. Someone will chime in with some info.

The shields are from a DS650, found it while searching the forum. Not sure where you could get the bowl spacers from, maybe Vforcejohn has some. With the spacers, you need to extend the main jet so it sits further into the bowl.

anyone else experience this?

you're running stock carbs though????

If so than that's not really an issue.......unless on the off chance you are pulling enough fuel through the jets to run the bowls low

Like he said the main thing that would move or could be jiggled by the rough hoops---or change because of the angle the bike is on would be the floats---Or possibly something with the fuel pump---Ya know the little over flow tube that comes out right by the water pump---Is there any indication that gas is dripping there---Have you tried to blow the bowls out around the floats to see if at an angle they or oneof them gets hung up on something.
